Description

General part information

SK040N Series

40 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. Alternistor type devices only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability.
